Today at school we learned about electromagnets. We wrapped the wire one quarter of the way around the bolt. We tested it and it wasn’t that strong. Next we wrapped the wire halfway on the bolt. We tested it. It was stronger than before, it held 6 paper clips. Next we wrapped the wire all the way up the bolt. We tested it and it worked. It picked up a lot of paperclips. Electromagnets are a type of a magnet that need a battery and wire to make it a magnet. Electromagnets need electricity.
Questions I have are:1. how is a magnet made? 2.how else can you make a magnet?
